The discharge valve adopts a material scraper installed on the same axis, a rotor formed by a feeding impeller and a stator composed of a valve flange, a clapboard with feed openings and a cylindrical valve material chamber with dumping holes on the bottom board. Wherein, the scraper is fixed on the shaft end over the clapboard; the feeding impeller is installed in the valve material chamber; the valve flange is connected with the flange at the lower port of the hopper to make the scraper enter the cone bottom of the hopper. A valve shaft is driven by a speed regulating motor acceleration and deceleration machine via a cone gear of 90 degree or a sprocket gear and a chain to realize the coaxial rotation of the scraper and the impeller, which dumps the powder material difficult to dump by piles and realizes the ration adjustable dumping.
Description
The present invention relates to a kind of adjustable speed granular material discharge valve.Belong to the mechanical field feeding device.
Discharge valve in existing uses of industry such as building materials, chemical industry and medicine mainly is star-like discharge valve.This valve has better seal, is suitable for granular, flowing power preferably granular material discharging big with bulk density.And, viscosity little for bulk density is big, the fine dry powder of flowing power difference or the granular material of high-moisture, even the hopper cone angle narrows down to 40 degree, material also usually can paulin in feed hopper bottom, discharging more can not be quantitatively regulated in normally discharging; Therefore be not suitable for the discharge valve that automatic production line makes to regulate feeding coal.
At the above-mentioned deficiency of prior art, the invention provides a kind of adjustable speed granular material discharge valve, the shortcoming that has overcome star discharge valve paulin material and can not quantitatively regulate discharging can realize that bulk density is little, viscosity big, the fine dry powder of flowing power difference and the quantitative scalable discharging of high-moisture granular material.
The present invention adopts following technology to realize above-mentioned purpose.
1, adopts by the rotor that panel seat and two isosceles trapezoid scraper plates, impeller base and two or four rectangle impeller blades constitute of scraping that is installed on the same axle and replace star rotors; By being fixed on the dividing plate that has charging hole above the valve flange and being welded in below the valve flange, the cylinder valve that base plate has dumping pit and discharge duct is installed constitutes the stator of valve; Scraper plate is fixed on axle head on the valve curtain with scraping panel seat, and the feed impeller is installed in the valve body material chamber, scrapes between panel seat and the impeller base trundle is installed; And the valve flange is connected with feed bin end opening flange, makes scraper plate enter the hopper cone base.
2, make the isosceles limit, the outside of isosceles trapezoid scraper plate and the gap of hopper awl wall remain on 0.2-1.0mm, scraper plate base and the spacer gap under it are 0.1-0.5mm; The gap that the top margin of feed impeller vane and base keep 0.1-0.5mm with the indoor bottom surface of dividing plate and valve body material respectively; The outer side edges of blade and valve body cylinder inner wall keep the gap of 0.1-0.5mm; Dividing plate charging hole and base plate dumping pit keep 180 degree arranged in dislocation.
3, bush seat is installed on valve shaft top, axle bottom installation shaft bearing supports; Conical gear or sprocket gear that 90 degree are installed in the axle lower end drive with buncher acceleration and deceleration machine, make scraper plate and impeller coaxial rotation, and rotating speed can be regulated in 3-30 rev/min of scope.
By above-mentioned measure, realized that bulk density is little, viscosity is big, the fine powder of flowing power difference and the quantitative scalable discharging of high-moisture granular material.
Fig. 1 is this discharge valve structural representation (this figure is chain gear).Hopper (1) cone angle 40-60 degree.Panel seat (4) is fixedly scraped by nut (3) in valve shaft (2) upper end, is welded with the scraper plate (5) of two isosceles trapezoids on the seat symmetrically.The dividing plate (6) of band dumping pit is fixed on above the valve flange (9) with threaded pin (10), and the valve flange is fixed on the hopper flange (8) with bolt (7).The cylinder of valve body (15) is welded on below the valve flange, is with dumping pit on the base plate, and discharge duct (16) is installed.Dumping pit and charging hole dislocation 180 degree are installed.Four rectangular paddle (12) are welded on the impeller base (13) symmetrically.Scrape trundle (11) is installed between panel seat and the impeller base.Gland cover (14) is fixed on the valve body base plate.Discharge tube (16) is fixed on the below of base plate discharge port.The bearing seat (21) of the bush seat (17) on axle top and axle bottom is fixed on the support (18).Support is fastened on the support (19).The axle lower end is equipped with hinge wheel (20).Reductor (23) output axle head is installed little sprocket gear (22), and input shaft end is equipped with plunging joint (24); Another termination buncher (25) of plunging joint.Use chain gear between the big minor sprocket.Select reduction ratio as required, make the valve shaft rotating speed between 3-30 rev/min.
The operational process and the mechanism of discharge valve of the present invention are as follows: because scraper plate and feed impeller coaxial rotation, the material of feed hopper bottom is just constantly scraped among the valve body material chamber by scraper plate, pushes discharge port by impeller blade again, falls into barrel and draws off.After hopper bottom material was blown off, because the sliding force that bed of material gravity decomposes is greater than the bonding force of material with hopper awl wall, upper materials glided successively continuously, and it is indoor constantly to be scraped pan feeding, so the situation of paulin material can not occur.And material chamber volume is certain, and in certain range of speed, rotating speed improves, and the discharging amount increases, and has realized the quantitative discharging of scalable thus.
With the star discharge valve relatively, discharge valve of the present invention can be realized the quantitative discharging of scalable of the material that is difficult to draw off, but does not have sealing function.
The utility model is suitable for that various bulk densities are little, viscosity is big, the fine dry powder of flowing power difference and the quantitative scalable discharging of high-moisture granular material.
Embodiment: hopper cone angle 42 degree; The wide 80mm of scraper plate is with hopper awl wall gap 0.5mm; Valve body material chamber size is ф 145 * 21mm; The wide 20mm of impeller blade, outer side edges and valve chamber circumferential inner wall gap 0.5mm.Drive chain gear, 3-30 rev/min of axle rotating speed with the 0.37kw buncher.Material is the big fine powder of diatom earth of 1-5 μ viscosity, and natural bulk density is 0.17g/cm3.During axle rotating speed 5r./m., discharge rate is 197.4g/m., and being converted to volume is 0.23L/p.r.; During axle rotating speed 7.5r./p.m., discharge rate is 260.0g/m., and being converted to volume is 2.0L/r.; When the axle rotating speed was 25r./m., discharge rate was 810.2g/m., and being converted to volume is 0.19L/p.r..
